Embodiment 2

(14) A gas-liquid mixing device of a beverage is as shown in FIG. 3. The difference from the embodiment 1 is that the precooling liquid container inlet 14 is in an elbow structure and is connected with the container cover 11 in a fastening manner; the liquid flows out of the liquid outlet 13 of the liquid precooling pipe is transmitted to the precooling liquid container inlet 14; an outlet of the precooling liquid container inlet 14 faces a side wall of the container 1; a collision position of the liquid and the container wall may be above or below the liquid level of the liquid in the container; the liquid precooling pipe (not shown in the figure) avoids a liquid flow ejected from the precooling liquid container inlet 14 by a tensile or bias method and the like; and in addition, the precooling liquid container inlet 14 may also be formed in the side wall of the container to eject the liquid to another side wall of the container.

(15) Compared with the prior art, the invention adds a liquid refrigeration pipe in the gas-liquid mixing device and the refrigeration device outside the container to precool the liquid before mixing and increase the dissolution rate of the gas in the liquid. At the same time, the external cooling is not required for the prepared liquid, the size of the equipment is reduced, and the application scope of the equipment is expanded. The liquid molecule expander arranged increases the distances between the liquid molecules, further increases the dissolution rate of the gas and ensures that the liquid beverage with a high gas content is produced.
